It prevents the user from directly touching the device when getting the hand sanitizer, which can further prevent cross-infection among users, thus ensuring hygiene and health.

BACKGROUND OF THE INVENTION

The present invention relates to hand sanitizer dispensation and more particularly pertains to a hand sanitizer dispenser.

The pump-type hand sanitizer dispenser currently used in public places usually requires people to use their hand to directly touch the discharge part to squeeze out the liquid. Since different people repeatedly touch the same part with wet hands during use, it is very easy to cause the spread of bacteria or viruses among the users. In hospitals, it is more likely to cause disease transmission, especially during surgical hand washing and hand disinfection when the requirements for the liquid dispensation manner are higher, and the hand-squeeze type obviously cannot meet the requirements.

In addition, the general liquid dispenser is fixed on the wall and cannot be moved, thus resulting in limited scope of application and inconvenient use.

Furthermore, most of the existing liquid dispensers do not have a pressing mechanism suitable for use by the disabled, so that the disabled cannot use them.

BRIEF SUMMARY OF THE INVENTION

In order to overcome the above-mentioned shortcomings of the prior art, an object of the present invention is to provide a hand sanitizer dispenser that can be operated by a pedal and is simple and reliable in structure, large in capacity and flexible to use, so as to ensure the users' hygiene and health on the one hand, and improve the convenience of operation on the other hand. Another object of the present invention is to provide a device that is supplemented by manual pressing to get hand sanitizer, so that it can be used by both able-bodied and those with inconvenient or disabled legs, thereby improving the applicability of the device.

The objects of the present invention is achieved by the following technical solutions:

A hand sanitizer dispenser, comprising a hand sanitizer bucket, a storage chamber, a liquid suction pipe, a push-type liquid suction pump, a liquid outlet pipe, a support base, a hollow vertical pole, a transmission rod assembly and a pedal mechanism. The hollow vertical pole and the storage chamber are both arranged on the support base. The hand sanitizer bucket is stored in the storage chamber. The hand sanitizer bucket is filled with hand sanitizer. The liquid suction pipe has a first end which communicates with the hand sanitizer bucket and a second end which communicates with a liquid inlet of the push-type liquid suction pump. The push-type liquid suction pump is arranged at an upper end of the hollow vertical pole. The liquid outlet pipe has a first end which communicates with a liquid outlet of the push-type liquid suction pump and a second end which is exposed outside the hollow vertical pole. The transmission rod assembly is arranged in the hollow vertical pole in a vertically movable manner. The transmission rod assembly has an upper end which abuts against the push-type suction pump in transmission and a lower end which cooperates with the pedal mechanism in transmission. The pedal mechanism is arranged on the support base, and pedal operation of the pedal mechanism can drive the transmission rod assembly to push up and press the push-type liquid suction pump, thereby causing the push-type liquid suction pump to suck the hand sanitizer in the hand sanitizer bucket through the liquid suction pipe and spray it out through the liquid outlet pipe.

Further, it further comprises a pressing handle rotatably pivoted on a side of an upper part of the hollow vertical pole. The pressing handle has a first end which extends into the hollow vertical pole to cooperate with the transmission rod assembly in transmission and a second end which is a pressing end and is exposed outside the hollow vertical pole. Pressing operation of the pressing end of the pressing handle can also drive the transmission rod assembly to push up and press the push-type liquid suction pump, thereby causing the push-type liquid suction pump to suck the hand sanitizer in the hand sanitizer bucket through the liquid suction pipe and spray it out through the liquid outlet pipe.

Further, the push-type liquid suction pump comprises a pump body, a plunger, a plunger spring, and a pump cover. The pump body is provided with a pump cavity with an upward opening. The liquid inlet of the push-type liquid suction pump is arranged at a lower end of the pump body and communicates with the pump cavity.

A liquid outlet channel connecting the liquid outlet and the liquid outlet pipe is formed in the plunger. The pump cover covers the upward opening of the pump body and can prevent the plunger from being axially separated from the pump cavity. The upper end of the transmission rod assembly abuts against the pump body. When the transmission rod assembly pushes upward and abuts against the pump body, the pump body moves upward relative to the plunger and squeezes out air in the pump cavity. When the transmission rod assembly returns downwards, the pump body returns downwards under action of the plunger spring and sucks the hand sanitizer in the hand sanitizer bucket through the liquid suction pipe to spray it out through the liquid outlet pipe.

Further, the hollow vertical pole has an open top end which is equipped with a top cover. The upper end of the hollow vertical pole is also provided with an opening for the liquid outlet pipe to be exposed. An inner end of the liquid outlet pipe is connected with an abutment cap abutting against a lower end of the top cover. The upper end of the plunger abuts against the abutment cap.

The pedal has a first end which extends into the hollow vertical pole to cooperate with a bottom end of the lower transmission rod in transmission, and a second end which is a stepping end and is exposed outside the hollow vertical pole.

Further, the bottom end of the lower transmission rod is fixedly connected with a transmission abutting member, and two bottom sides of the transmission abutting member are respectively provided with a first abutting mating surface and a second abutting mating surface, each of which has a concave arc-shaped structure. The pedal has an inserting end which is provided with a left abutting block and a right abutting block, each of which has a concave arc-shaped structure. The left and right abutting blocks are in abutting cooperation with the first abutting mating surface and the second abutting mating surface.

Further, a guide pole is provided in the hollow vertical pole, and a lower end of the guide pole is fixed on the stand. The lower transmission rod is slidably sleeved on the guide pole in a vertically movable manner.

Further, the hollow vertical pole has an outer wall which is provided with a liquid receiving box below and corresponding with an outlet of the liquid outlet pipe. The upper end of the hollow vertical pole is also fixedly provided with a billboard on a side facing away from the liquid outlet pipe. The support base is provided with fixing holes for fixed connection with an external supporting surface.

Further, the storage chamber comprises a barrel-shaped case fixed on the support base and abutting on one side of the hollow vertical pole as well as a locked cover that is securely locked to an opening of an upper end of the barrel-shaped case by a lock.

DETAILED DESCRIPTION OF THE INVENTION

Hereinafter, the present invention will be further described in detail with reference to the embodiments given in the accompanying drawings.

As illustrated in FIG. 1 to FIG. 8, the hand sanitizer dispenser described in this embodiment comprises a hand sanitizer bucket 1, a storage chamber 2, a liquid suction pipe 3, a push-type liquid suction pump 4, a liquid outlet pipe 5, a support base 6, a hollow vertical pole 7, a transmission rod assembly 8 and a pedal mechanism 9. The hollow vertical pole 7 and the storage chamber 2 are both arranged on the support base 6. The hand sanitizer bucket 1 is stored in the storage chamber 2, and the hand sanitizer bucket 1 is filled with hand sanitizer. The liquid suction pipe 3 has a first end which communicates with the hand sanitizer bucket 1 and a second end which communicates with a liquid inlet 401 of the push-type liquid suction pump 4. The push-type liquid suction pump 4 is arranged at an upper end of the hollow vertical pole 7. The liquid outlet pipe 5 has a first end which communicates with a liquid outlet 402 of the push-type liquid suction pump 4 and a second end which is exposed outside the hollow vertical pole 7. The transmission rod assembly 8 is arranged in the hollow vertical pole 7 in a vertically movable manner. The transmission rod assembly 8 has an upper end which abuts against the push-type suction pump 4 in transmission and a lower end which cooperates with the pedal mechanism 9 in transmission. The pedal mechanism 9 is arranged on the support base 6, and pedal operation of the pedal mechanism 9 can drive the transmission rod assembly 8 to push up and press the push-type suction pump 4, thereby causing the push-type suction pump 4 to suck the hand sanitizer in the hand sanitizer bucket 1 through the liquid suction pipe 3 and sprays it out through the liquid outlet pipe 5.

The hand sanitizer dispenser further comprises a pressing handle 10 rotatably pivoted on a side of an upper part of the hollow vertical pole 7. The pressing handle 10 has a first end which extends into the hollow vertical pole 7 to cooperate with the transmission rod assembly 8 in transmission and a second end which is a pressing end and is exposed outside the hollow vertical pole 7. Pressing operation of the pressing end of the pressing handle 10 can also drive the transmission rod assembly 8 to push up and press the push-type liquid suction pump 4, thereby causing the push-type liquid suction pump 4 to suck the hand sanitizer in the hand sanitizer bucket 1 through the liquid suction pipe 3 and spray it out through the liquid outlet pipe 5.

As mentioned above, as an implementation structure for the transmission cooperation of the pressing handle 10 and the transmission rod assembly 8, the transmission rod assembly 8 is provided with an avoidance sliding slot 801. The avoidance sliding slot 801 has an upper end which is horizontally provided with an abutting pin 8011. The pressing handle 10 has an insertion end 101 which penetrates into the vertical sliding slot 801 and cooperates in abutment with a lower side of the abutting pin 8011. When the pressing end 102 of the pressing handle 10 is pressed down, the insertion end 101 of the pressing handle 10 rotates upward and drives the transmission rod assembly 8 to move upward via the abutting pin 8011. When the transmission rod assembly 8 moves upward according to the pedal operation of the pedal mechanism 9, the pressing handle 10 will not be driven under the avoiding action of the avoidance sliding slot 801, thereby avoiding mutual interference.

Specifically, the push-type liquid suction pump 4 comprises a pump body 41, a plunger 42, a plunger spring 43, and a pump cover 44.
